Description

Technical Field

[0001] This utility model relates to the field of nitrogen generation equipment technology, specifically a novel silencer. Background Technology

[0002] A nitrogen generator is a device that uses air as raw material and separates oxygen and nitrogen in it using physical methods to obtain nitrogen gas. Industrial nitrogen generators can be divided into three types according to different classification methods: cryogenic air separation, molecular sieve air separation, and membrane air separation. Nitrogen generators generate a lot of noise when they are working and need to be used in conjunction with a silencer.

[0003] Currently, most nitrogen generator silencers on the market use a single silencing method, which mainly relies on the silencing medium (such as glass fiber cotton and ceramic cotton) filled inside the silencer to insulate against high-velocity gases. However, this silencing method often has limited silencing effect and cannot meet the demand for efficient silencing of nitrogen generators. In addition, after a period of use, the silencing medium easily adsorbs fine dust particles and impurities, and its silencing effect will gradually decrease. However, the existing silencing medium is filled inside the silencer, making it difficult to replace the silencing medium, which further affects the long-term use effect and performance of the silencer.

[0004] Therefore, a new type of silencer is needed to solve the problems of poor silencing effect due to the single silencing method of the existing nitrogen generation silencer, and the difficulty in replacing the silencing medium when its effectiveness declines. Utility Model Content

[0005] The purpose of this invention is to provide a new type of silencer to solve the problems in the prior art where the silencer for nitrogen generation has a single silencer method, resulting in poor silencer effect, and the silencer medium is not easy to replace when its effectiveness declines.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel muffler, comprising an exhaust pipe, a muffler housing being fastened to the outer surface of the exhaust pipe, a sliding ring being slidably connected to the inner surface of the muffler housing, an isolation net being fixedly connected to the right outer wall of the sliding ring, a fixing plate being fixedly connected to the right outer wall of the isolation net, and mounting mechanisms being provided at both ends of the right side of the outer surface of the muffler housing;

[0007] Each set of the installation mechanism includes a column, which is fixedly connected to the outer surface of the muffler housing. A sliding cavity is coaxially formed inside the column, and a rod is coaxially arranged inside the sliding cavity. A sliding plate that slides with the sliding cavity is fastened to the outer surface of the rod. A spring is sleeved on the outer surface of the rod. One end of the rod slides through the outer wall of one end of the column and is provided with a pull ring.

[0008] It should be noted in the solution that an outer cylinder is fastened to the outer surface of the muffler housing, a water injection pipe is fixedly connected to the top left side of the outer surface of the outer cylinder, and a drain pipe is fixedly connected to the bottom right side of the outer surface of the outer cylinder.

[0009] It is worth noting that the side wall of the fixing plate has multiple circumferentially distributed vent holes, and slots are provided at both ends of the outer surface of the fixing plate corresponding to the two insertion rods. A pull rod is fixedly connected to the center of the right outer wall of the fixing plate.

[0010] Furthermore, it should be noted that a feed pipe is fixedly connected to the top left side of the outer surface of the muffler housing, and positioning holes are provided through the two slots at both ends of the outer surface of the muffler housing.

[0011] In a preferred embodiment, a connecting flange is fixedly connected to the outer wall of the left side of the exhaust pipe, and a sealing cap is provided at the bottom of the drain pipe and the top of the feed pipe.

[0012] In a preferred embodiment, the inner surfaces of the sliding ring and the isolation mesh are slidably engaged with the outer surface of the exhaust pipe, and the outer surface of the fixing plate is slidably engaged with the inner surface of the muffler housing.

[0013] In a preferred embodiment, the ends of the two insert rods away from the corresponding pull rings pass through the corresponding positioning holes and are inserted into the corresponding slots. The two ends of the two springs are respectively fixedly connected to one end wall of the corresponding sliding cavity and one end outer wall of the corresponding sliding plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The silencer housing is filled with silencing medium through the feed pipe and water is injected into the outer cylinder through the water injection pipe. The silencing medium insulates the gas, and the water in the outer cylinder insulates and dampens the silencer housing. The high efficiency of the nitrogen generator is achieved through internal and external sound insulation, which effectively avoids the problem of poor silencing effect caused by the single silencing method of nitrogen generator silencers.

[0016] 2. Pull the insert rod and slot together to release the limiting position on the fixing plate. Use the pull rod to remove the sliding ring, isolation net and fixing plate from inside the muffler housing, thereby bringing the silencing medium out of the muffler housing. This makes it easy to replace the silencing medium. The operation is simple and effectively avoids the problem of not being able to replace the silencing medium when its performance deteriorates.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-4 As shown, this utility model provides a technical solution, including an exhaust pipe 1, a muffler housing 2 is fastened to the outer surface of the exhaust pipe 1, a sliding ring 3 is slidably connected to the inner surface of the muffler housing 2, an isolation net 4 is fixedly connected to the right outer wall of the sliding ring 3, a fixing plate 5 is fixedly connected to the right outer wall of the isolation net 4, and an installation mechanism 6 is provided at both ends of the right side of the outer surface of the muffler housing 2.

[0024] Each set of mounting mechanisms 6 includes a column 61, which is fixedly connected to the outer surface of the muffler housing 2. A sliding cavity 62 is coaxially opened inside the column 61. A rod 63 is coaxially arranged inside the sliding cavity 62. A sliding plate 64 that slides with the sliding cavity 62 is fastened to the outer surface of the rod 63. A spring 65 is sleeved on the outer surface of the rod 63. One end of the rod 63 slides through the outer wall of one end of the column 61 and is provided with a pull ring 66.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that an outer cylinder 7 is tightly fitted onto the outer surface of the muffler housing 2. A water injection pipe 8 is fixedly connected to the top left side of the outer surface of the outer cylinder 7, and a drain pipe 9 is fixedly connected to the bottom right side of the outer surface of the outer cylinder 7.

[0026] Further as Figure 2, Figure 3 and Figure 4 As shown, it is worth noting that the side wall of the fixing plate 5 has multiple vent holes 10 distributed in a circular pattern, and slots 11 are provided at both ends of the outer surface of the fixing plate 5 corresponding to the two insertion rods 63. A pull rod 12 is fixedly connected to the center of the right outer wall of the fixing plate 5.

[0027] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a feed pipe 13 is fixedly connected to the top left side of the outer surface of the muffler housing 2, and positioning holes 14 are provided through the two slots 11 at both ends of the outer surface of the muffler housing 2.

[0028] Further as Figure 1 and Figure 2 As shown, it is worth noting that a connecting flange 15 is fixedly connected to the outer wall of the left side of the exhaust pipe 1, which facilitates the connection of the exhaust pipe 1 to the exhaust end of the nitrogen generator through the connecting flange 15. The bottom end of the drain pipe 9 and the top end of the feed pipe 13 are both equipped with sealing caps 16. When the silencer is working, the drain pipe 9 and the feed pipe 13 are sealed to prevent the silencing medium inside the silencer shell 2 and the water inside the outer cylinder 7 from leaking.

[0029] Further as Figure 2 As shown, it is worth noting that the inner surfaces of the sliding ring 3 and the isolation net 4 slide against the outer surface of the exhaust pipe 1, and the outer surface of the fixing plate 5 slides against the inner surface of the muffler housing 2. This makes it easy for the staff to pull the lever 12 to remove the sliding ring 3, the isolation net 4 and the fixing plate 5 from the inside of the muffler housing 2, thereby facilitating the replacement of the muffler medium.

[0030] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the ends of the two insert rods 63 away from the corresponding pull rings 66 pass through the corresponding positioning holes 14 and are inserted into the corresponding slots 11. Through the cooperation between the insert rods 63 and the slots 11, the fixing plate 5 is locked and limited. The two ends of the two springs 65 are respectively fixedly connected to one end wall inside the corresponding sliding cavity 62 and one end outer wall of the corresponding sliding plate 64. Through the elastic action of the springs 65, the movement and reset of the insert rods 63 are facilitated.

[0031] In summary: When using this silencer, firstly, connect the exhaust pipe 1 to the exhaust end of the nitrogen generator via the connecting flange 15. Then, open the sealing cap 16 at the top of the feed pipe 13 and inject the silencing medium into the silencer housing 2 through the feed pipe 13. After injection, seal the feed pipe 13 with the sealing cap 16. Then, inject water into the outer cylinder 7 through the water injection pipe 8. When the nitrogen generator starts working, the gas enters the exhaust pipe 1. At this time, the silencing medium filled inside the silencer housing 2 provides sound insulation for the high-velocity gas. After passing through the silencing medium, the gas is discharged through the exhaust port 10. At the same time, the water filled inside the outer cylinder 7 provides sound insulation and vibration damping for the working silencer housing 2. Through internal and external sound insulation, the nitrogen generator is effectively silenced, which avoids the problem of poor silencing effect caused by a single silencing method in nitrogen generator silencers.

[0032] When the silencing medium inside the muffler housing 2 needs to be replaced, pull the two pull rings 66 simultaneously to move the slide plate 64 inside the sliding cavity 62. When the slide plate 64 slides, it causes the insertion rod 63 to separate from the slot 11, thereby releasing the limiting fixation of the fixing plate 5. Then, the sliding ring 3, the isolation net 4, and the fixing plate 5 are removed from the inside of the muffler housing 2 by the pull rod 12. During this process, the silencing medium inside the muffler housing 2 can be brought out. Then, the sliding ring 3, the isolation net 4, and the fixing plate 5 are reinserted into the inside of the muffler housing 2. Under the action of the spring 65, the insertion rod 63 is pushed back into the slot 11 to re-fix and limit the fixing plate 5. Then, the new silencing medium is filled into the inside of the muffler housing 2 through the feed pipe 13 to complete the replacement of the silencing medium. The operation is simple and effectively avoids the problem of not being able to replace the silencing medium when its performance deteriorates.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
